My DM is using this homebrew version of True Strike - too powerful?

3.5 replacements:

1. Do not scale number of d4s.

1b. Instead add 1d6 damage per tier.

2. Take the best of the d4s, not the sum.

3. Revert to baseline. Then add 1d12 damage per tier to the true stike attack.

I go with 3. 1b is a modification on 1, the rest are independent suggestions.

So the thing that I keep coming back to is that it's called "True Strike".

There are a few things it can be balanced around:
A) Increasing accuracy and damage
B) Increasing accuracy only (to eventually be a guaranteed hit)
C) Increasing damage only

Option C doesn't make a lot of sense for a Cantrip called "True Strike". The only classes that I think would use Option B are rogue and paladin. Option A seems to be what most here have recommended.
